Answer:
D. Electron transport chain
Explanation:
The transport chain is an electrical and chemical continuum of four protein molecules that redox in pairs, leading to the formation in a mechanism called oxidative phosphorylation, of ATP. It exists both in mitochondrial and photosynthesis in mitochondria.

please help me guys
[tex]\Large\textbf{ACTIVE AND PASSIVE IMMUNITY}[/tex]
Active Immunity, Immunity which is acquired by the own immune response of the body.
Passive Immunity, Immunity which is acquired and dependent upon the antibodies transported from another person or even an animal. A person's immune system does not acquire or make the antibodies itself. A newborn baby acquires passive immunity from its mother through the placenta.
x---------------------------------------------------x
[tex]\Huge\text{Vaccination:}[/tex]Vaccination is a artificial active immunity. Artificial because the antibodies are not acquired by any natural infection but it is injected into the healthy body of the person. It is Active immunity because the body does not get already made (from other animal) antibodies but it acts on the small amount of the pathogen which is injected in the body and acquires the antibodies itself. So the person acquires antibodies naturally acting on the antigen. Antigen is any foreign agent which triggers the immune system to produce antibodies against it. Vaccines contains antigen which is a harmless form of the bacteria or a virus that causes the disease you are being immunised against. The bacteria or virus are in small proportion and greatly weakened in the vaccine so they just trigger an immune response without causing any real damage. When Vaccine is injected in the body, the immune system starts to make antibodies of different forms against the antigen(Virus or bacteria in the vaccine). When the appropriate shape antibody reacts with the antigen and forms antibody-antigen complex which destroys the antigen. This means that type and shape of antibody is perfect to work against that antigen, then the immune system start forming only those kind of antibodies in great proportion and the Person gets immunised by the vaccine in a natural way.

A reflex response to excessive pain or heat is first processed through the brain.
True
False
Answer:
False
Explanation:
The above statement is false
False because reflexes and snap reactions are generally bounced back directly from the spinal cord to save time. An example could be touching something hot because you react and move away instantly rather than your body burning for a second while the brain processes the information.

What will be the long-term consequences if the hunts of baby deer continue? If they stop?
Answer:
If people continue to kill baby deer then the population will start to decrease and if they stop killing them then the deer population will increase. If the deer population increase than that won't be a good thing for the environment because they will then be everywhere. Plus where there is prey there is predator so the predators of the deer will also increase in population.

A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
There is no mother cell after a paramecium divides because it is divided by binary fission and the paramecium is divided into two identical cells, called daughter cells, there is no mother cell left.
What is paramecium?Paramecium is a protist. It is oval-shaped with cilia all over the body, and it is minute and can be seen only under a microscope. It engulfs its food through the body cavity, which is its mouth.
Binary fission means when the cell is divided into two daughter cells. The division is asexual reproduction. The cell divided DNA into two copies and then each cell gets the DNA.
Thus, there is no mother cell after a paramecium divides since binary fission is used and the paramecium is split into two identical cells, known as daughter cells.

if a cell does not go through the s phase of the cell cycle before mitosis what might be wrong with the daughter??
Answer:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
